Participated projects: , The Fusion framework, Design System, Fix Header Imports (to make transition to Swift possible), Click&Collect, Search Page Redesign (+ multicolumn layout), Group Buy, fix of FirebaseRemoteConfig, New Feeds, Short Videos, New Reviews Gallery, Performance Metrics Library (+ Grafana charts setup), in-app infrastructure for Affiliate Program, etc.Mentored 3 juniors. Sometimes led iOS+android+QA team: consulting with people, prioritization, taking decisions.Conduct interviews all the time: Swift stage, iOS platform stage, algorithm stage, Mobile System Design stage, final stage. Up to 3 interview per week in hot time. Prepare materials for interviewing.Write docs for processes like: kind of release process, kind of internal communications process.

Fixed some bugs in Design System library. Implemented dark theme support for 3 screens.

I implemented two new landing screens for Loyalty Program. Profiled hotel's cell scrolling and increased cell's display speed by about 5%, also proposed further refactoring to increase display speed by about 50%. Refactored old calendar component. Made it extendable, and then extended it to support: (A) very flexible outfit setup, and (B) two new types of calendar with different logic. Adjusted multiple screens to support Right-To-Left languages. As always fixed bugs along the way.Worked with: PinLayout, SnapKit, LayoutKit, Deep links (a little bit), XCode::Instruments::Time profiler, Swift, Objective-C, etc.

Development of iOS client-app for "MB"-project in company http://www.bpcbt.com Supported legacy Objective C code. Fixed bugs. Also I wrote some building scripts with bash and Swift-command-line. Wrote Unit-tests with Quick/Nimble. Rewrote some old pieces of code to Swift, also wrote several new parts of app in Swift. Worked in distributed team of 11 developers. Sometimes took part in discussions on requirements for new tasks. A couple of times participated in interviewing of candidates for "iOS developer" vacancy. Major part of my work was to review code of merge requests of remote and local developers.

I worked on CYBRUS iOS-client app. This app was implemented in Objective-C. Our team created native part of app in about half of the year from zero level up to upload to AppStore. I was following company Coding Guidelines to ensure that code quality is enough to support app and to release updates. I took part in: code review, new feature discussions. I have presented full solution for iPad screen composition of app.I have implemented about 15 screens of app as individual contributor. And I worked with code of most of other UIViewControllers, i.e. screens of authorization (3 ones), final variant of registration screens (4 ones), list of profiles, list of recent, list of contacts, lists of participants (many of them), different settings screens. Using NSURLSession I have implemented communication with REST-server for SMS-registration. I have implemented cached asynchronous update mechanism for ContactsList screen. I have designed and implemented screen-routing system for safe UIViewControllers presentation.

Realization and support of native part of Streege app (about 10 screens). Setup of native part inter-operation with cross-platform C++ code which was maintained by other developer.Streege was released to App Store, and was available as iPhone app.

Research in area of appliances of numerical solutions of PDE. Some simple C++ programming. Refactoring of Matlab-and-Fortran software package. Package was intended for numeric computations.

I lectured on C++ programming and programming with Windows and POSIX API.
